ANSWER EXPLANATIONS FOR PREVIOUS PAGE
1.
E
Set up a proportion with the information you have and the information you are looking for:
height
24 ft
x ft
=
=
length of shadow
6 ft
18 ft
Do the cross-multiplication to find that x = 72 feet, choice (E).
2.
G
Remember that Sherwood’s $100 payment covers both his one-time new-member fee and a
few months of a membership. Since the new-member fee is $16, this means that Sherwood put
$100 – $16 = $84 toward his monthly fees. Since each month costs $14, Sherwood paid for
$84 ÷ $14 = 6 months of membership.
3.
B
Although this looks like a problem in which you’ll need to factor, you actually can just substitute
y2 − 4
(−6)2 − 4
the y value: y − 2 = (−6) − 2 =
(36) − 4 32
=
= −4.
−8
−8
4.
J
Because the group ended up with more than 15 students, they overpaid. Figure out the total
amount they should have paid and subtract it from the amount that they did pay: (18)($11.50) –
(18)($10.25) = $22.50.
5.
C
When you are finding a probability, you need to figure out a basic part/whole relationship. In this
case, there are 16 members in the orchestra, but only 12 of them are eligible to become speakers,
so the “whole” (the denominator) must be 12. If you selected choice (B), you forgot to omit the
1
4 soloists. The likelihood that Itzhak would be chosen for this person is therefore , because he
12
represents one possibility out of the twelve eligible for the speaker position.
6.
H
In order to find the perimeter of a rectangle, remember that there are four sides. In this case the
four sides add up as follows: 8 ft + 8 ft + 17 ft + 17 ft = 50 ft. If you selected choice (F), you may
have only added two sides of the rectangle, and if you selected choice (J), be careful—this is the
area!
7.
B
Work slowly through this problem. The group has sold 240 passes online at $9 each. This means
that they have already made (240)($9) = $2160. In order to reach their goal, they will need $4000
– $2160 = $1840. Since the question asks how many in-person tickets they will need to sell, you
can approximate how many tickets will get them $1840 by dividing: $1840 ÷ $12 = 153.333. Since
there is no such thing as 0.333 tickets, you have to round up to get 154 tickets, choice (B).

explanations from our flagship Cracking series!
ANSWER EXPLANATIONS FOR PREVIOUS PAGE
1.
C
Choice (C) is correct because the third paragraph states that “God Bless the Child” was familiar
mostly to adults. Because of this, it is more likely that the song would be familiar to Monique’s
parents, who must be adults, than it would be to her friends, who are presumably high school
students and not yet adults. Choice (A) is incorrect because the passage never identifies “God Bless
the Child” as a Rodgers & Hammerstein number. Choice (B) is incorrect because the passage does
not support the extreme claim that “God Bless the Child” is the most sophisticated Billie Holiday
song. Choice (D) is incorrect because Monique’s song choice is presented as a contrast to the overly
enthusiastic choices of her peers.
2.
J
Choice (J) is correct because the passage initially describes Monique and her friends as aloof,
because they isolate themselves in the auditorium and Monique acts like a monarch with a
royal court, and disparaging, because they are anxious to belittle the other students during their
auditions. Choice (F) is incorrect because, although the passage describes that most students are
nervous about going first, this does not describe how Monique and her friends are presented.
Choice (G) is incorrect because, although Monique and her friends react to Esperanza’s song choice
with disbelief, that is not how they are initially portrayed in the passage. Choice (H) is incorrect
because Monique and her friends are portrayed as being unfriendly and excluding.
3.
A
Choice (A) is correct because the passage states that Esperanza did not look up until she got to
center stage and then looked only at Mrs. Dominguez. Choice (B) is incorrect because the passage
says she shuffled her feet on her walk to the stage, which is not a confident stride. Choice (C) is
incorrect because the passage states she was paying little attention to the other auditions. Choice (D)
is incorrect because the passage only states that she was working on her geometry homework, not
that she finished it.
4.
J
The question is asking for the rhetorical effect of the statement But not this year. The previous
paragraph establishes that students generally dread the first audition slot and relates the tense
manner in which Monique used to view the first slot. The paragraph that follows this phrase
explains that Monique had decided to embrace the first slot as a means of surprising her peers.
Choice (J) is correct because it identifies the statement in question as a contrast between the status
quo and Monique’s surprising decision. Choice (F) is incorrect because the passage provides no
evidence that most students have resolved their fears of going first, only that Monique has. Choice
(G) is incorrect because the passage never establishes the extreme claim that this year’s audition
was the strangest yet. Choice (H) is incorrect because the passage does not go on to describe any
different imagery Monique associates with the uncomfortable first slot but rather to say she is no longer
uncomfortable with it at all.

6.
J
Based on Table 1, the salt solution increased the amount of rust every day. On Day 8, the sample
had 1.84 g of rust, so on Day 9 the amount of rust would likely be higher than 1.84 g, choice (J).
7.
B
The formula shows that when rust is produced, H2 is also produced, so choice (B) is the only
possible correct answer.
8.
J
Table 1 shows that the salt solution produced 0.56 g Fe2O3 on Day 2. Figure 1 shows that the
water buffered to pH " 10.0 had less than 0.50 g Fe2O3 until Day 8, so the only correct answer is
choice (J).
9.
A
Table 1 shows that the sugar solution produced 0.11 g Fe2O3 by Day 6 and 0.19 g by Day 8. The
amount produced from Day 6 to Day 8, then, would have been 0.19 – 0.11 " 0.08 g.
